Explanation

Using the neutralization formula:
M₁V₁ = M₂V₂

Given:

• M₁ (HCl) = 0.50 M
• V₁ (HCl) = 10 mL
• M₂ (NaOH) = 0.25 M
• V₂ (NaOH) = ?

Now, solving:
(0.50 M) (10 mL) = (0.25 M) (V₂)
5 = 0.25V₂
V₂ = 20 mL

Kepler's Third Law of Planetary Motion states:

T² = (4π²/G * (M₁ + M₂)) * a³

Where:

T = Orbital Period

a = Semi-major Axis

G = Gravitational Constant

M₁ and M₂ = Masses of the two bodies (e.g., planet and star)

This law shows that the square of the orbital period (T) is proportional to the cube of the semi-major axis (a).
